Some embodiments relate to a method of controlling speed of a variable speed generator. The method includes detecting a load of the variable speed generator and determining a target speed for the variable speed generator based on the load supplied by the variable speed generator. The method further includes using a controller to adjust the speed of the variable speed generator based on the target speed. The method may further include correcting the target speed by calculating a correction factor that corrects the target speed based on a voltage produced by the variable speed generator.

1. A method of controlling speed of a variable speed generator comprising: detecting a load supplied by the variable speed generator;determining a target speed for the variable speed generator based on the load supplied by the variable speed generator;using a controller to adjust the speed of the variable speed generator based on the target speed; andcorrecting the target speed including calculating a correction factor that corrects the target speed based on a voltage produced by the variable speed generator, and wherein calculating a correction factor that corrects the target speed based on a voltage produced by the variable speed generator includes scaling the target speed by the correction factor. 2. The method of claim 1, wherein detecting a load supplied by the variable speed generator includes sensing AC current produced by the variable speed generator. 3. The method of claim 1, wherein detecting a load supplied by the variable speed generator includes sensing DC current produced by the variable speed generator. 4. The method of claim 1, wherein detecting a load supplied by the variable speed generator includes sensing power produced by the variable speed generator. 5. The method of claim 1, wherein detecting a load supplied by the variable speed generator includes using the controller to detect the load on the variable speed generator. 6. The method of claim 1, wherein determining a target speed for the variable speed generator based on the load supplied by the variable speed generator includes determining a target speed from a data table. 7. The method of claim 6, wherein determining a target speed from a data table includes performing linear interpolation from a two-point data table. 8. The method of claim 1, wherein determining a target speed for the variable speed generator based on the load supplied by the variable speed generator includes multiplying the load by a factor and adding an offset. 9. The method of claim 1, wherein correcting the target speed includes using a proportional-derivative controller to correct the target speed. 10. A power generation system comprising: a variable speed generator that operates at different speeds and is configured to provide power to a load;a controller that detects the load supplied with power by the variable speed generator, wherein the controller determines a target speed for the variable speed generator based on the load supplied with power by the variable speed generator, andwherein the controller adjusts the speed of the variable speed generator based on the determined target speed of the variable speed generator, wherein the controller corrects the determined target speed, wherein the controller corrects the target speed by calculating a correction factor that corrects the target speed based on a voltage produced by the variable speed generator, wherein the controller corrects the target speed by calculating a correction factor that corrects the target speed based on a voltage produced by the variable speed generator, and wherein the controller calculates the correction factor that corrects the target speed based on a voltage produced by the variable speed generator and scales the target speed by the correction factor. 11. The power generation system of claim 10, wherein the controller senses power produced by the variable speed generator to detect the load supplied by the variable speed generator.
